A side pillar air curtain guide includes a main body having a ramp receiver and an air curtain ramp insert connected to the main body. The air curtain ramp receiver insert includes a plurality of ribs projecting from the main body at an acute included angle with the main body.

A shock absorber formed such that at least part of an end wall of a groove rib is a fragile portion, or a shock absorber that makes a fracture behavior according to a design intent. The shock absorber has a hollow molded-body having a hollow. The hollow molded-body includes front and rear walls that are spaced from and opposed to each other and a side wall that connects the front and rear walls. The side wall is provided with a front groove rib formed by recessing the front wall and a rear groove rib formed by recessing the rear wall. A side groove wall is formed by welding together at least parts of end walls of the front groove rib and the rear groove rib.

An armrest includes a protruded section extending in a vehicular front-rear direction and protruded toward a vehicular interior side, and the protruded section includes an upper section, a lower section, and an intermediate section that is between the upper section and the lower section and connects the upper section and the lower section on a vehicular interior side. The armrest further includes ribs that are on a vehicular exterior side with respect to the intermediate section and arranged in the vehicular front-rear direction and each of the ribs extends from the upper section to the lower section. The ribs include a low rigidity rib and a high rigidity rib that are arranged next to each other in the vehicular front-rear direction, and the high rigidity rib having rigidity higher than that of the low rigidity rib.

A plastic component for an interior of a vehicle comprises: a first piece including a first support element; and a second piece facing the first piece and including a second support element adjacent to the first support element within an interstice between the first piece and the second piece; wherein, the first support element extends from an interstice-facing surface of the first piece at a junction, and the junction has a junction thickness that is less thick than a thickness of the first support element adjacent to the junction. During the transition from a non-impact position to an impact position, the junction can separate to induce breakage of the first piece in the interstice between the first piece and the second piece and not viewable from the interior of the vehicle.

An upper reinforcement for a door trim panel includes a reinforcement channel, and a rib extending across the reinforcement channel. More particularly, the rib includes a first end section that engages a first wall of the channel, a second end section that engages a third wall of the channel and an intermediate section that extends across a window in the second wall of the channel.

A vehicle pillar structure is provided including a pillar frame that configures framework of a pillar and that includes a flange portion configuring an attachment counterpart for a weather strip at a vehicle front-rear direction rear end portion of the pillar frame, a garnish that is attached to a vehicle width direction inner side of the pillar frame and that configures a styling face of a vehicle cabin interior, and plural ribs that are integrally formed to a face of the garnish on the pillar frame side, that are supported by the flange portion through the weather strip, and that are arrayed in a pillar length direction.

A strengthening structure of a vehicle is provided herein and includes a base having cutouts. Relief members are disposed across the base and each include a cross section having twelve or fourteen corners, a distal end, and an open proximal end in communication with a corresponding cutout.

A shock absorber to be mounted on a vehicular exterior side of a trim member includes a plate member having a plate surface and to be mounted on a vehicular exterior surface of the trim member such that the plate surface of the plate member is along the vehicular exterior surface of the trim member, and at least two or more shock absorbing members that are arranged on a vehicular exterior surface of the plate member to be spaced from each other along the plate surface of the plate member.

An upper reinforcement for a door trim panel includes a reinforcement channel, softening features within reinforcement channel, a tab depending from the reinforcement channel, and a trigger feature between the reinforcement channel and the tab whereby the reinforcement channel is released from the tab during a side impact. A method of tuning performance characteristics of the upper reinforcement is also described.
